Compliance with regulatory bodies is essential to operate businesses, maintain tenants, and stay within the bounds of the law for local, state, and federal level for many industries. One common area of focus is around Energy. Reducing energy, lowering greenhouse emissions, and reducing carbon footprints are ways of meeting and exceeding sustainability initiatives across the globe. Employing an energy management strategy with highly accurate power meters is one way to track where energy is going and implement corrective actions to improve the planet.
ASHRAE 90.1 is a standard for measuring energy in commercial buildings. It covers many aspects of energy management, such as total consumption, HVAC and lighting systems, and individual circuits. For buildings over 10,000 square feet, with or without tenants, it is necessary to have multi-load branch energy monitoring equipment.
There are many conditions that need to be met to fully comply with the ASHRAE 90.1 standard, but at the heart of the energy monitoring section of the standard is Chapter 184.108.40.206 Monitoring section requires the monitoring of each of the following separately: Total energy consumption for the entire building, HVAC systems, Interior lighting, Exterior lighting as well as receptacle circuits. Multi-load meters enable a cost effective solution to meeting this chapter in particular.
ISO 50001 is a voluntary standard that provides the guidance and framework for organizations to support their sustainability goals and reduce the overall impact on the environment through energy conservation.
The six key parts of the standard focus on:
Power meters are a simple and effective way to support an ISO 50001 strategy and give building owners, employees, tenants, and managers the data they need to create a safe and sustainable work and living environment.
Whether called Multi-Load, Multi Circuit, Multi Channel or even Branch Circuit energy metering, Setra’s line of power meters lower the cost per metering point and measures with more granularity than other metering solutions on the market.
Measure More... For Less
Identify what's going to be metered
Look across the installation and identify the equipment that are to be measured to support energy strategy
Examples: Chillers, Lighting, AHU’s, Tenant Usage
Count up how many CT’s are needed
Match the CT amperage to the breaker feeding the load or use Patrol Flex Coils (up to 1500A)
Single-Phase Service = 1CT
Split-Phase Service = 2 CT’s
Three Phase Service= 3 CT’s
Select Meter Part Number
Take the CT count and select the meter with the right number by matching the CT’s with available inputs
SPM03EDN = 3 CT inputs
SPM12EDN = 12 CT inputs
SPM48EDN = 48 CT inputs
